    • Bio-fertilisers are living microorganisms of bacterial, fungal and algal origin. Their mode of action differs and can be applied alone or in combination.So, Statement 1 is correct and Statement 3 is not correct.
    • Pseudomonas and Bacillus species are the predominant plant growth-promoting bacteria. Many heterotrophic bacteria live in the soil and fix significant levels of nitrogen without direct interaction with other organisms. Examples of this type of nitrogen-fixing bacteria include species of Azotobacter, Bacillus, Clostridium, and Klebsiella.
    • The application of Bacillus-based fertilizers to soil can enhance the plant-available forms of nutrients in rhizospheres, control disease-causing pathogenic microbial growth and induce pest defence systems.
    • Pseudomonas has been reported to have the potential to improve plant biomass, relative water content, leaf water potential and root adhering soil/root tissue ratio. The function of zinc is to help the plant produce chlorophyll.So, Statement 2 is not correct.
